Description
本发明涉及回收装置技术领域,尤其是涉及一种海面油品回收装置。The invention relates to the technical field of recovery devices, in particular to a sea surface oil recovery device.
石油及其产品在开采、炼制、贮运和使用过程中进入海洋环境而造成的污染。各种含油废水、海上船舶压舱水和洗舱水的排放,油船遇难、输油管道和近海石油开采的泄漏等,都是海洋石油污染的重要途径。估计世界经由各种途径入海的石油每年约600余万吨。石油污染会破坏海滨景观和浴场。海面上的油膜能阻碍大气与海水之间的气体交换,影响海洋植物的光合作用。海兽的皮毛和海鸟羽毛被石油沾污后,就会失去保温、游泳或飞翔能力。石油污染物还会干扰海洋生物的摄食、繁殖和生长发育,改变鱼类的洄游路线,沾污渔具和渔获物,使海产品带有石油味而不能食用,严重造成海洋的生态破坏。The pollution caused by the entry of petroleum and its products into the marine environment during mining, refining, storage, transportation and use. All kinds of oily waste water, the discharge of ballast water and tank washing water of ships at sea, the wreck of oil tankers, the leakage of oil pipelines and offshore oil exploitation, etc., are all important ways of marine oil pollution. It is estimated that the world's oil entering the sea through various channels is about 6 million tons per year. Oil pollution will destroy the seaside landscape and bathing places. The oil film on the sea surface can hinder the gas exchange between the atmosphere and seawater, and affect the photosynthesis of marine plants. When the fur of sea animals and the feathers of seabirds are contaminated with oil, they lose their ability to keep warm, swim or fly. Petroleum pollutants can also interfere with the feeding, reproduction, growth and development of marine organisms, change the migratory routes of fish, contaminate fishing gear and catches, make seafood smell of petroleum and make them inedible, and seriously cause ecological damage to the ocean.
入海石油首先在重力、惯性力、摩擦力和表面张力的作用下,在海洋表面迅速扩展成薄膜,进而在风浪和海流作用下被分割成大小不等的块状或带状油膜,随风漂移扩散。风是影响油在海面漂移的最主要因素,油的漂移速度大约为风速的百分之三。在沿岸发现的漂油,冬季在半岛北岸较多,春季在半岛的南岸较多,也主要是风的影响所致。石油中的氮、硫、氧等非烃组分是表面活性剂,能促进石油的扩散。这就对海面油品的回收工作造成了一定程度的困难。The oil that enters the sea first expands into a thin film on the ocean surface under the action of gravity, inertial force, friction force and surface tension, and then is divided into block or ribbon oil films of different sizes under the action of wind waves and ocean currents, drifting with the wind diffusion. Wind is the most important factor affecting the drift of oil on the sea surface, and the drift speed of oil is about 3% of the wind speed. The oil drift found along the coast is more in the north coast of the peninsula in winter and more in the south coast of the peninsula in spring, which is also mainly caused by the influence of wind. Non-hydrocarbon components such as nitrogen, sulfur, and oxygen in petroleum are surfactants, which can promote the diffusion of petroleum. This has caused a certain degree of difficulty in the recovery of oil products on the sea surface.
目前,在原油开采的过程中,海洋石油平台排入海中的生产水内往往含有部分原油,这就造成原油对海洋环境造成污染,同时也会对石油资源造成浪费。因此,妥善处理海面泄露油品,对于改善海洋污染、减少资源损失、保护海洋 生态环境等具有关键性的作用。At present, in the process of crude oil extraction, the production water discharged into the sea by offshore oil platforms often contains some crude oil, which causes crude oil to pollute the marine environment and also wastes oil resources. Therefore, proper handling of oil spills on the sea surface plays a key role in improving marine pollution, reducing resource loss, and protecting the marine ecological environment.

上述海面油品回收装置在使用时,包括以下步骤:When the above-mentioned sea surface oil recovery device is in use, the following steps are included:
回收过程:开始收集待回收油水混合物时,第一水泵301开始工作,待回收油水混合物通过第一水泵301被吸收至输液管,待回收油水混合物经过输液管通过单向阀302后进入分离舱103内,单向阀302可防止油水混合物回流至输液管内。Recovery process: when the oil-water mixture to be recovered starts to be collected, the first water pump 301 starts to work, the oil-water mixture to be recovered is absorbed into the infusion pipe through the first water pump 301, and the oil-water mixture to be recovered passes through the infusion pipe through the one-way valve 302 and then enters the separation cabin 103 Inside, the one-way valve 302 can prevent the oil-water mixture from flowing back into the infusion tube.
分离过程:油水混合物通过输液管连续进入油水分离系统2的分离舱103内,由于水和油重力作用,水相透过分子半透膜201进入至储水舱102内,且油相被拦截在分离舱103内,随着第一水泵301持续将油水混合物至分离舱103内,在压力的作用下,粗分离后的油水混合物由吸水管202底部入口进入,穿过整段吸水管202后并由吸水管202顶端流出进入至储油舱101内,而储油舱101内达到一定压力时,减压阀6打开将内部压力排空。Separation process: The oil-water mixture continuously enters the separation compartment 103 of the oil-water separation system 2 through the infusion pipe. Due to the gravity of water and oil, the water phase penetrates the molecular semi-permeable membrane 201 and enters the water storage compartment 102, and the oil phase is intercepted in the In the separation compartment 103, as the first water pump 301 continues to pump the oil-water mixture into the separation compartment 103, under the action of pressure, the roughly separated oil-water mixture enters from the bottom inlet of the suction pipe 202, passes through the entire section of the suction pipe 202, and The water flows out from the top of the water suction pipe 202 into the oil storage tank 101, and when a certain pressure is reached in the oil storage tank 101, the pressure reducing valve 6 is opened to discharge the internal pressure.
搜集过程:第二水泵401开始工作时,储水舱102内的水相通过输水管303被输送至储存舱的出液口,因此具有向前运动的动力;并由控制机构403来控 制方向舵402工作,装置的运动会产生方向变化。Collection process: when the second water pump 401 starts to work, the water phase in the water storage tank 102 is transported to the liquid outlet of the storage tank through the water delivery pipe 303, so it has the power to move forward; and the control mechanism 403 controls the rudder 402 To work, the movement of the device produces a change in direction.
当液位传感器5监测到进入储油舱101的油品液位高度高于阈值时,第一水泵301停止工作,海面油品回收工作结束,即可遥控至回收点回收。当液位传感器5监测到进入储油舱101的油品液位高度不高于阈值时,第一水泵301维持工作,继续海面油品回收工作。When the liquid level sensor 5 detects that the liquid level of the oil entering the oil storage tank 101 is higher than the threshold, the first water pump 301 stops working, and the recovery of the oil on the sea surface is completed, and the oil can be recovered at the recovery point by remote control. When the liquid level sensor 5 detects that the liquid level of the oil entering the oil storage tank 101 is not higher than the threshold value, the first water pump 301 keeps working and continues to recover the oil on the sea surface.
工作原理:working principle:
装置工作时,首先油水收集系统3开始工作,油水混合物通过第一水泵301进入输液管中,通过连接在输液管底部的单向阀302进入油水分离系统2的分离舱103,同时单向阀302可防止分离舱103内的油水混合物逆流,分离舱103下方与分子半透膜201相连,上方有一小口通向吸水管202,油水混合物进入分离舱103后,由于密度原因,油相会覆盖于水相上方,又因重力影响与分子半透膜201的作用,下方的水相会向下透过分子半透膜201进入储水舱102,油相则被分子半透膜201拦截,第一水泵301向分离舱103持续输送油水混合物,也就相当于给分离舱103持续加压,由于压力影响,上方的油相会进入吸水管202,吸水管202内填充高吸水性的聚丙烯酰胺材料,将进入管的油相中混合的少量水相进行分离,当油相通过整个吸水管202后进入储油舱101内部,储油舱101内部压力不断上升,当达到减压阀6设定值时,储油舱101内的压力排出,同时进入储油舱101的油相为经过粗分离的油水混合物中的油相,储水舱102内部的第二水泵401可将分离出的水相排出装置的同时为装置提供动力,同时正对于出水口设置的方向舵402可改变动力的方向,因此装置可以实现对海面油品的动态回收;设置在装置上方的储气舱104为密封状态,与装置各个部分无物质交换,在液位传感器5检测到油相收集到达阈值后,装置将停止海面油品收集工作,这时储气舱104将发挥作用,储气舱104内储存的气体将保证 装置在收集大量油品后依然有足够的浮力防止装置沉入海中,同时在收集过程中储气舱104也可以保证装置浮于海面,且确保第一水泵301可吸收油水混合物。When the device works, first the oil-water collection system 3 starts to work, and the oil-water mixture enters the infusion pipe through the first water pump 301, and enters the separation compartment 103 of the oil-water separation system 2 through the one-way valve 302 connected at the bottom of the infusion pipe, while the one-way valve 302 It can prevent the oil-water mixture in the separation chamber 103 from flowing backwards. The bottom of the separation chamber 103 is connected to the molecular semipermeable membrane 201, and a small opening on the top leads to the water suction pipe 202. After the oil-water mixture enters the separation chamber 103, the oil phase will cover the water due to the density. At the top of the phase, due to the influence of gravity and the effect of the molecular semipermeable membrane 201, the water phase below will pass through the molecular semipermeable membrane 201 and enter the water storage tank 102, while the oil phase will be intercepted by the molecular semipermeable membrane 201, and the first water pump 301 continuously transports the oil-water mixture to the separation chamber 103, which is equivalent to continuously pressurizing the separation chamber 103. Due to the influence of pressure, the oil phase above will enter the water suction pipe 202, and the water suction pipe 202 is filled with a highly water-absorbent polyacrylamide material. Separate a small amount of water phase mixed in the oil phase entering the pipe. When the oil phase passes through the entire water suction pipe 202 and enters the interior of the oil storage tank 101, the internal pressure of the oil storage tank 101 continues to rise. When it reaches the set value of the pressure reducing valve 6 , the pressure in the oil storage tank 101 is discharged, and the oil phase entering the oil storage tank 101 is the oil phase in the roughly separated oil-water mixture, and the second water pump 401 inside the water storage tank 102 can discharge the separated water phase to the device provide power for the device at the same time, and at the same time, the rudder 402 that is set against the water outlet can change the direction of power, so the device can realize the dynamic recovery of oil products on the sea surface; There is no material exchange in the part. After the liquid level sensor 5 detects that the oil phase collection reaches the threshold, the device will stop the oil collection work on the sea surface. After collecting a large amount of oil, there is still enough buoyancy to prevent the device from sinking into the sea. At the same time, the gas storage chamber 104 can also ensure that the device floats on the sea surface during the collection process, and ensure that the first water pump 301 can absorb the oil-water mixture.
